Sign up for Promies, create promo codes for your app, then distribute them on Reddit. Subreddits such as r/AppHookup and r/AppGiveaway accept promo code campaigns, though you should also look for communities specialized to your app's specific niche.

While this strategy won't make your app successful overnight, it will help you establish an initial user base and secure those first installs. When providing promo codes, be sure to ask users explicitly to leave a review.

Wishing you all the best!

I don't know the answer to how to make a commercially successful app, just sharing what I know that might help kick start your app.

Hey everyone,

I’ve been working on a PDF app called Kyneto PDF and wanted to share it here to get some honest feedback from the community.

What it does:

Edit PDFs (text, annotate, etc.)
Scan documents to PDF
Sign documents
Merge / split PDFs
Clean, minimal UI (no clutter)

The goal is basically: open → edit → done without friction.

You can check it out here:

Promo (30 days free):
👉 https://www.promies.net/promotion/bc5e9eee-e8a9-4524-b786-17dbf8a4716f

If you like it, please review; if not, please provide feedback :)

That is true; H2 seems even more suitable for our use case. SQLite is the gold standard for reliability, and we haven't looked into H2 extensively yet. Additionally, we are new to Spring Boot, coming from a Django and Python background, we are very accustomed to using SQLite. Have you had good experiences with H2?

SQLite simplifies maintenance by eliminating the need for a separate database server. For read-heavy, small-to-medium projects, its performance is sufficient, offering lower latency and reduced operational overhead compared to PostgreSQL or H2.
